The story of Steven Avery has been transformed from a simple murder trial to an issue of international interest following the Netflix series Making a Murderer.

However now Netflix have been accused to leaving out key pieces of evidence by one of the prosecutors who worked Avery’s case.

Ken Kratz declined to be interviewed for the documentary, however he has now said that ’80 to 90 per cent’ of the forensic evidence was left out of the series.

He also told People magazine: ‘You don’t want to muddy up a perfectly good conspiracy movie with what actually happened, and certainly not provide the audience with the evidence the jury considered to reject that claim.’

Making a Murderer follows the true story of Steven Avery, who was released from prison after 18 years for a rape which he did not commit.

However after his exoneration he was convicted of murder.

The documentary claims that there are several gaps in the evidence and trial which convicted Avery.
